This paper presents the design and implementation of a power supply unit for zone-less induction cook-top. Here a control algorithm is also presented for tracking the user activity which includes misalignment of pan above the coil and removal of pan. The control algorithm is implemented using a DSP processor. The power supply consists of a power stage, control stage, and digital control algorithm...
Induction heating (IH) appliances are widely used for industrial appliances and home electronics because IH has a lot of merits. Recently, wireless power transfer attracts attention as a promising industry. As for wireless power transfer, inductance is changed in accordance with power transmission distance or surrounding environment. Similarly as for IH, inductance and resistance as equivalent circuit...
Based on the demands of TEA CO2 laser, high power, high-precision and high repetitive rate charging technologies of capacitor charging power supply was discussed in the paper. Capacitor charging power supply adopted series resonant circuit has constant current and "fixed voltage steps" charging characteristics which were analyzed in the paper in theory. Because of the constant current charging...
Modern high-frequency induction heating technology puts forward higher requirements for load matching of the induction heating power supply. LLC resonant load circuit can replace the traditional induction heating load matching transformer, and increase power density. This paper analyzes the load matching characteristics of LLC load resonant circuit in high frequency induction heating power supply,...
Novel high frequency converter cum Inverter analyzed mathematically and simulated with less number of controlled switches in the converter stage of a capacitor charging power supply. Series resonant based capacitor charging power supply (CCPS) is more popularly used to charge pulsed power systems. The power supply size, weight and cost increases with increase in charging rate. So, an attempt has been...
